1. Electrostatic adsorption film formation mechanism

Powder spraying achieves the combination of coating and workpiece through high-voltage electrostatic field:

Charge transfer: The spray gun releases a high-voltage electric field to make the powder particles negatively charged

Electric field attraction: The grounded workpiece surface forms a positive electric field to attract charged powder

Uniform coverage: Powder accumulates on the workpiece surface to form a dense coating (complex shapes are optimized by auxiliary spray guns)

2. Automated assembly line architecture

Modern powder spraying lines integrate three core systems:

Conveying system: adjustable speed chain adapts to different workpiece sizes and production rhythms

Control center: PLC programming supports multiple groups of processes Parameter storage and quick call

Detection module: Online film thickness monitoring and AI vision system collaboration, real-time feedback adjustment

III. Implementation path of environmental protection technology

Material recycling: Excess spray powder is reused through a multi-stage recovery system

Energy optimization design: The curing furnace uses heat recovery technology to reduce energy consumption

Waste treatment: Pre-treatment waste liquid is chemically treated to achieve resource utilization

IV. Typical application scenarios

Automobile manufacturing: High adhesion coatings are suitable for complex curved parts

Construction industry: Weather-resistant coatings ensure long-term use of outdoor profiles

Home appliance production: Environmentally friendly coatings meet food-grade contact standards
